How to Understand
十五
十五 is the Chinese word for the number fifteen. It represents the quantity 15 in the decimal system and is used in both formal and informal contexts to indicate a numerical value.
The character 十 means 'ten,' and 五 means 'five.' Together, they form 十五, literally meaning 'ten plus five.' This structure reflects the base-10 counting system commonly used in Chinese and other languages.
In daily life, 十五 is often used in dates, ages, and measurements. For example, it can refer to a person's age (十五岁, shí wǔ suì) or a date (十五号, shí wǔ hào). It also appears in traditional festivals, such as the Mid-Autumn Festival, which falls on the fifteenth day of the eighth lunar month.
